Note 1: 100% production tested at T
Note 2: The device is powered from input IN2.
Note 3: The RESET output is guaranteed to be in the correct state for IN1 or IN2 down to 1V.
Note 4: Monitored voltage (+3.3V, +3.0V) is also the device power supply. Supply current splits as follows: 25µA for the resistor-
